    Reverse osmosis is one of the most effective membrane-based water treatment methods, providing businesses with water of the highest purity. It is based on membrane technology, in which a pump forces water through a very fine membrane. The membrane lets only water molecules through, while removing most of the dissolved substances \u2013 salts, heavy metals, organic compounds, bacteria and viruses.<\/p>

    Thanks to their excellent filtration capability, RO solutions are used in industries where water purity directly affects the reliability of production processes and the quality of the final product. Thanks to their excellent purification capability, reverse osmosis systems are widely used in water utilities, the food industry, the energy sector, boiler houses, hotels and spas, and other industries where it is important to ensure consistent water quality and high productivity.<\/p>

    Miridon always configures reverse osmosis systems based on the water analysis and the company’s consumption needs, ensuring maximum efficiency and reliability.<\/p>

    For comparison:<\/span> <\/span><\/p>

    • Viruses: 0.02-0.4 microns<\/span> <\/span><\/li>
    • Bacteria: 0.2-10 microns<\/span> <\/span><\/li>
    • RO membrane pore: 0.001 microns<\/span> <\/span><\/li><\/ul>

      For fresh water, the unit operates at a pressure of 2\u201317 bar, and for seawater at over 40 bar. The exact operating pressure depends on the type of membrane used.<\/span> <\/span><\/p>

      RO membranes can remove, for example, fluoride, boron, chloride, nitrates, radium and other unwanted substances from the water. For customers with higher consumption, the reverse osmosis unit is selected according to the water analysis and the nature and volume of consumption.<\/span> <\/span><\/p>
